Application March 5, 194?,Serial No. 732,551 I (Cl. 21(l--90) 1 Claim. 1

A This invention relates to new and useful improvements and structural refinements in water filters, and the principal object of the invention is to provide a device of the character herein described, which is particularly adapted for use in association with water conduits from eave troughs, so as to prevent leaves and other foreign material from passing to a sewer and probably obstructing the same.

Water filters or strainers are commonly employed at the junction of the cave trough with the downwardly extending conduit, but such strainers, by virtue of their location, are poorly accessible, so that they may not be readily inspected for the presence of obstructions, nor can they be conveniently cleaned, except by persons particularly equipped to do so. It is, therefore, a further object of the invention to provide a filter which is adapted for positioning within a short distance above the ground, so that inspection and cleaning thereof may be easily and conveniently effected.

Another object of the invention is to provide a filter in which the cleaning element may be quickly and easily removed when so desired.

An additional object of the invention is-to provide a filter which is simple in construction, which will not easily become damaged. and which will readily lend itself to economical manufacture.

With the above more important objects in view and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the construction and arrangement of parts as shown in the accompanying drawings in which:

Figure l is a front elevation of the invention, partially broken away to reveal its construction.

Figure 2 is a cross sectional view, taken substantially in the plane of the line 2-2 of Figure 1.

Figure 3 is a side elevational view, taken substantially in the plane of the line 3-3 of Figure 1, but showing the sliding door in the opened position.

Figure 4 is a cross sectional view, taken substantially in the plane of the line i-4 of Figure 3, and

Figure 5 is a cross sectional View, taken substantially in the plane of the line 5-5 of Figure 4.

Like characters of reference are used to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a water filter designated generally by the reference character I ii, the same embodying in construction a substantially rectangular housing or casing ll con.- sisting of a lateral wall I2 provided with a pair of end caps l3 and l4.

' The housing It is adapted to bedisposed in a substantially upright positionf and the caps l3, it are provided with suitable inlet and outlet ducts l5 and I6 respectively. The housing or casing may be attached to the adjacent wall of the building (not shown) or may be supported in position simply by being interposed in the length of the drain conduit which extends downwardly from the cave trough. In any event, the filter, as a whole, is positioned a short distance above the ground, and the passage of water through the filter is indicated by the arrows ll, as will be clearly understood.

One of the side walls of the casing H assumes the form of a slidable door l8 which is provided at the upper end thereof with an out-turned flange or finger piece 19 and is slidably positioned in a pair of opposed guides 20 provided on the lateral wall l2.

The casing ll contains a removable box-like filter unit 2! which is formed from suitable wire mesh material and is open at the upper end thereof, as indicated at 22. It will be noted that this open end of the filter unit is disposed adjacent to the inlet duct i5 and, if desired, the inner end portion 23 of the latter may be flattened to a substantially elliptical form, so that the water entering the unit 2! through the duct '5 is more evenly distributed.

For convenience in handling, the unit 2| may also be equipped with a handle 24 and the size of the unit is such that it is spaced virtually on all sides from the walls of the casing II, as will be clearly apparent.

The filter unit 2! is supported in position by means of an inverted V-shaped support bracket 25 which is rigidly secured adjacent to the lower end of the casing. It will be also observed that the filter unit centered by means of a pair of V-shaped guides 26, provided on the opposed inner surfaces of the casing walls l2.

When the invention is placed in use, the unit 2! will effectively gather leaves and other foreign material, and by virtue of the spacing of the filter unit with respect to the casing, the passage of water through the filter will not be obstructed.

The condition of the filter unit may be readily inspected by simply opening the door l8, and if necessary, the filter unit may be conveniently withdrawn for cleaning purposes.

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further de" scription thereof at this point is considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

A debris separating trap for drain pipes comprising an elongated casing including a pair of side walls, a pair of end walls and upper and lower walls, one of said end walls having a longitudinal access opening, a slidable closure carried by the casing for closing the access opening, guide means fixed within the casing slidably receiving the closure, inlet means carried by the upper wall of said casing and outlet means carried by the lower wall of said casing, a screened receptacle positioned within the casing and having a bottom, an elongated substantially horizontal support arm fixed to and projecting laterally from one end wall of said casing, said arm being spaced between the side walls of said casing and disposed above the lower wall of said casing, said arm bearing against the bottom of said receptacle and forming the sole support for said receptacle, and horizontal spacer strips fixed to the inner faces of said side walls and bearing against said receptacle to space the receptacle from the side walls of said casing.
